Biology 2021- SA MPLE GENETIC PROBLEMS pea plant. If a 1. The gene for tall is dominant over dwarf in the garde what heterozygous tall plant is crossed with a dwarf plant, the genotype and phenotype of the offspring? 2. If brown eyes were dominant over blue eyes, explain eyed parents could have a blue-eyed child. of 3. Assume that curly hair (C) is dominant to straid, What are curly-haired parents have a straight genotypes? Pens have a straight-haired child. What are the pare Brachydactyly (short fingers) (B) is dominant to the What is 4. A heterozygous brach ydactylous man marries a normal woman. the chance that: a. b. their first child will be brachydactylous. all their three children will be brachydactylous. C.None of their three children will be brachydactylous. 5. Given that cystic fibrous is autosomal recessive, if two individuals carriers of the cystic fibrous trait have children, what is the pr children will have cystic fibrous? probability that their Given the information in ? 5, consider what if one person has cystic fibrous and 6. the other person has two normal alleles, what is the probability their children will have cystic fibrous? 7. In humans, the allele for blood type A and the allele for blood type B show co-dominance. A person with both alleles has blood type AB. Both A and B dominates type O. A person with an allele for blood type A and type O marries someone with an allele for blood type B and type O. List the types of blood their offspring could have and the probability for each blood t in the offspring. ype A voung lady with blood type O gave birth to a baby with blood type O. In a court case she claims that a certain young man is the father of her child. The nan has type A blood. Could he be the father? Can it be proven on this evidence that he is the father? lone If brown eyes are dominant over blue eyes and a brown eyed man mardes blue eyed woman, what color eyes might their offspring have?Explanation / Answer
1. Let "T" be the dominant allele for the height of plant and "t" be the recessive allele.
Heterozygous tall plant genotype - Tt
Dwarf plant genotype - tt
Tt x tt
Genotypic ratio: 1:1
Phenotypic ratio - 1:1
